Recently, I was getting close to Google’s free storage limit, and the storage manager showed that Gmail was using most of it.I wanted a simple way to see my attachments in one place, download the files I wanted to keep, and remove emails with attachments I no longer needed. Gmail search can find emails with attachments, but it doesn’t provide a convenient file-based view.So I built a browser extension called Mail Attachment Lens. It lets me search and filter attachments, download files, and move the source emails to Bin. It also helped me uncover quite a few attachments I had completely forgotten about.I decided to publish it in case anyone else finds it useful.It’s free and open source. There’s no backend, so mailbox data stays between the extension and Google.
